$A$ is incorrect. Pretend you are standing on the line segment which touches a corner of the cube. Orient yourself so you are facing the this corner. Then the line which touches the side is to your left, but on $A$ it is to the right. So the answer can't be $A.$

The answer is $B.$ See if once you know the answer you have an easier time about the spacial reasoning.

Maybe I should have called it hint. Actually thats a method to solve also very hard problems of that kind, of course it is cheating but it can be used to control the result.

This is a very good method to get precisely one question right on the SAT.

@jspecter: I didn't say this method is good to apply it in a math test, its rather didactical.
